I've just bought an Argos mini oil-filled heater for £24.99 (800W)
because I don't like leaving my little computer room (to go and get
food etc) with the fan heater left switched on.

My lounge is fairly adequately kept warm when the computer's on, if
the heating was on earlier. I have the GCH running for 40 mins about
3x per day. Fan heater in the bedroom for about 10 mins before turning
in.

Yes, I, too, find the heat from the two computers makes a significant
difference over the course of the day (sometimes only one is on).
However, we are now experiencing VERY low temperatures (2 miles from
the Wash). I have also succumbed to a quick boost from a fan heater in
the bedroom before turning out the light. I am also religiously
closing all doors. It's been roughly 3¾ hours since I switched on the
new radiator and the Tschibo is reading 18.1 pence. The room is quite
comfortably warm now since I've been downstairs watching the news and
cooking supper etc.
